Installer failed at task `Configure AWS cloud provider` while enabling AWS cloudprovider for EC2 C5 instance.

Go through of the issue, it appears that ansible is unable to get `ansible_virtualization_role` and `ansible_virtualization_type` for EC2 C5 instance:

$ ansible -m setup all -i /tmp/c5_host |grep "virtualization"
        "ansible_virtualization_role": "NA", 
        "ansible_virtualization_type": "NA", 

Checked on the EC2 C5 instance:
